Another one that's vague enough that it could mean a lot of things. I was prepared for this to be a commentary on current events, but then the narrator wouldn't be blaming himself. So in the end, I guess it's a simple message about taking the responsibility for making the most of your life. Which is fine. It's just not doing it with much finesse.

Bang Bang
Maxwell's silver hammer slammed down upon my verse,
Bang Bang
Though I wrote vers libre and really kept it terse!

Not as big of a read on this one. The final line really narrows down the intent from basically any sort of life cut short/wasted to specifically having let life pass the perspective poet on by. Which is a valuable lesson, to be sure.

Though I am curious about the transitions from the bangs to the booms. I don't have a solid explanation for that, so I'm curious if anyone else has some thoughts, or what the author intended with the switch. We'll see in 9ish hours!
